Polyurethane resin
Anti-moisture elastic structure adhesive

Modified Specialty PU Resin

Component:

WINNATE-300A

WINCURE-300B

 

Application:

·Elastic structure adhesive to glue various substrates to produce decorative composite panel used in vehicle and building curtain wall.

 

Advantage:

·Non-filler, easy to process, without sedimentation or stratification within its validity

·Non-bubble issue led by moisture

·Clean for non-plasticizer added/non-thinner added

·Self-thickening ability, easy to layup

·Specially designed structure contribute to flame retardency

·Compatible with inorganic, metal, polar resin (PC/PET/PMMA/Nylon)
