Which products are UV resistant?

Glazing joints are highly susceptible to UV exposure. For this purpose, we therefore recommend the use of our silicone products that possess superior resistance to the aging process.

Hybrid and MS polymers have good resistance to UV. PU sealants and acrylics have a lower resistance. Because of this, hybrid polymers and PU sealants may be used for exterior joints, but not as glazing joints, the exception being Parabond Glazing.

Acrylic sealants can also be used outdoors but these are then best painted over to extend the life.
