AddWorks IBC 760 - Outstanding light and heat stabilizer for Silyl Modified Polymer (SMP) sealants

AddWorks IBC 760 is a mixture of a UV absorber, hindered amine light stabilizer (HALS) and antioxidant, and is designed to provide outstanding performance in SMP sealants in terms of light and heat stabilization. Available in micronized powder form, AddWorks IBC 760 prolongs the service life of SMP sealants as it reduces cracking and yellowing that typically occurs if exposed to strong sunlight or high temperature conditions.

 

The performance is evident when tested against current solutions in the market containing benzotriazoles. Our new stabilizer solution is an ideal ingredient to formulate high performance SMP sealants used for construction, automotive and other outdoor applications.
