Kestopur V 303
Kestopur V 303 is a two-component, foaming, solvent-free, polyurethane adhesive.
- Strong foam building
- Suitable for separate and spray application
Kestopur V303 adhesive's foaming properties are designed for the gluing of EPS insulation materials and mineral wool. Suitable materials are e.g. metals, insulation materials and fibre composite. Kestopur V 303 is used in conjunction with Kestopur 200/S hardener. Suitable for manufacturing sandwich elements on continuous press lines equipped with automatic applicator for two-component adhesives.

Kestopur V 303 is stored in a tightly closed original containers at +10–25° C for 6 months (1000 l container). After long storing, stir before use. Protect from freezing.
The surfaces to be bonded must be clean and dry. Remove oxides by sanding, and grease and other dirt with Kiilto Cleaner 303. The properly cleaned surface can be sanded and then primed with Kiilto Cleaning Primer to improve adhesion. Remove the sanding dust carefully prior to adhesive application. Kestopur V 303 resin must be stirred before use. Add Kestopur 200/S hardener to the resin, and mix until a uniform colour is achieved. Apply the adhesive on one or both sides of the materials to be bonded. Fresh adhesive stains are removed with a dry cloth and surfaces are wiped with Kiilto Cleaner 303 or Kiilto Cleaner 302. Hardened adhesive can only be removed by mechanical means. We recommend gluing at room temperature. Gluing can be carried out at below room temperature (even at 10 °C), but the hardening process will be slower and application may be affected
