WE PRODUCE ADHESIVE PRIMER - ADHESION PROMOTER

Kleberco KL303 and KL305 accelerate the initial adhesion and adhesion of double-sided and single-sided adhesive tapes and wrapping foils, as well as increases the final adhesion strength values ​​up to 30%. 

Kleberco KL303 and KL305 work as an adhesive that increases the adhesion of tapes and is used in many sectors to strengthen tape and increase strength in mounting tape, foam tape, double-sided tape, 3M VHB, Orafol UHB, Nitto Hyperjoint, Tesa ACX applications. It is also known as tape aid, tape reinforcing agent, tape primer, adhesion strength enhancer in Automotive, Household Appliances, Aviation, General Industry applications.

Kleberco KL303 and KL305 are not only used for reinforcement in tape bonding, but also In for strengthening adhesive wrapping foils, foils that have the status of one-sided adhesive tape, such as advertising foil and vehicle wrapping foil, and to permanently prevent edge lift. It is also known as a adhesive strengther, especially in the advertising industry.

Kleberco KL303 and KL305 work as a surface preparation liquid before bonding adhesive tapes and wrapping foils. 

1) First of all, the surfaces are cleaned with Isopropyl Alcohol (IPA, ipa). We also produce IPA wipes. For detailed information, you can visit our ISOPROPYL ALCOHOL WIPES page. 

2) If double-sided tape is to be attached, Kleberco KL305 is applied to both materials to be mounted and waited for at least 1 minute for the solvent evaporation of Kleberco KL305. You can use materials such as lint-free wipes, cloth, application tools for applying. If a single-sided tape or wrapping foil is to be adhered to, since there will be only one surface to be adhered to, Kleberco KL305 is applied as a thin layer on the relevant surface and waited for at least 1 minute for the solvent evaporation. This waiting period is valid for 23 degrees Celsius, and it is useful to extend the waiting time if working in winter or in a cold environment. After applying Kleberco KL305, you can proceed to the second step when you can visually observe solvent evaporation and only a thin film layer remaining on the surface.

3) After waiting for 1 minute for the solvent evaporation and only Kleberco KL305 adhesive remaining on the surface, double-sided adhesive tape or single-sided adhesive tape can be carefully mounted to the surfaces, taking care that there are no air bubbles under the tape. 

4) After the Kleberco KL305 application and adhesive tape bonding processes are completed, it is very important to apply pressure on the surfaces. This pressure will allow both the tape and Kleberco KL305 to penetrate the surfaces better, and if there are any air bubbles, it will allow the air to be evacuated from the edges, allowing the assembly to be flawless. If Kleberco KL303 is used as a wrapping foil edge sealant or wrapping foil adhesive reinforcer in the wrapping foil application, using a squeegee will be helpful to better spreading for strong adhesion of the adhesive foils, cast foils, vehicle wrap foils or advertising foils.

· Providing fast assembly application, which strengthens and increases the strength in the assembly of various materials with single-sided or double-sided adhesive tape in the general industry

Kleberco KL303 and KL305 are sold in different packages as 150ml, 250ml, 500ml, 1000ml, 5000ml and barrels. In addition, it is also sold as Kleber Primer Wipes, which is produced using Kleberco KL305 Adhesion Promoter product and does not open due to its special packaging structure, in order to provide ease of use and to be shipped with adhesive tape or tape-laminated.

The application of Kleber Primer Wipes is no different from the ones written above. A special lint-free cloth is used in Kleber Primer Wipes and Kleberco KL305 is soaked up this wipe, providing ease of use to end users. It is often purchased to ship with automobile and motorcycle accessory products, or with products that are adhesive laminated and sold to end users. In addition, it is used intensively in factories to clearly adjust the amount of primer usage during mass production.

You can also use Kleberco KL305 as a adhesion enhancer, strength enhancer for the applications of vehicle wrapping foils, advertising foils, cast foils, one way vision foils. 

Pay attention to the tight closure of the lid when not in use or during breaks in the application. In this way, you will both prevent unnecessary solvent evaporation and provide an economical application opportunity by using the product more.

In several industries, Kleber Primer (Kleberco KL305) is also known as an affordable primer, economical adhesion promoter, as the exact equivalent of 3M Primer 94. Kleber Primer application is just like 3M Primer 94, and it is sold as an equivalent of 3M Primer 94 as tape reinforcement, tape strength increase or wrapping foil edge sealant, wrapping foil reinforcer. Kleber Primer (Kleberco KL305) is offered in 4 different bottle packaging options as 150ml, 250ml, 500ml and 1000ml. It is an economical primer, economical surface preparation liquid, which is the exact equivalent of 3M Primer 94 in terms of performance.

Performance of the products sold as a 3M Primer equivalent or as a tape primer in the market (as it is known from the laboratory results) is unfortunately low. Adhesion strengths are not sufficient especially in materials with low surface energy such as TPO, TPU, TPE, TPV, PE, PP, EPDM, Rubber, that is, LSE materials and substrates, and even in materials such as aluminum, glass, metal, plastic, which are classified as normal surface energy. Kleberco KL303 and KL305 Primer give the closest results with 3M Primer in terms of performance. 

The point you should pay attention to while testing the adhesion of the primer on the surface is that 72 hours have passed. Since acrylic adhesives reach full curing values ​​after 72 hours, ie 3 days, we recommend that you do your comparative tests over 72 hours. For example, if you want to comparatively test an aluminum piece to be bonded to the glass, first prime a piece and glass with 3M Primer 94 and adhere the mounting tape, and then apply Kleberco KL303 or KL305, the equivalent of 3M Primer 94. After 72 hours, when you try to remove the materials from the surfaces by applying force, you will see that the performance is very close. Or you can apply the same test in another way. Stick one side of the double-sided mounting tape to the 3M Primer 94 applied surface and do not remove the protective paper on the tape. Stick to the same material on the surface on which Kleberco KL303 or KL305 is applied and again, do not remove the protective paper on the tape. Try to remove the tapes from the surface after 72 hours. You will see that results will be very close in terms of performance.
