New silicone resin: HAPS-free for high-heat applications

Monday, 31 August 2015

A new high-temperature resistant, high-solids silicone resin is HAPS-free (Hazardous Air Pollutant) and intended to provide protective properties in industrial applications.

No toxic substances release during curing, making application of "Silikophen AC 950” possible in enclosed spaces. Smoke formation and VOC content are lower than traditional bake-cure silicone resins, allowing the resin to meet the increasing requirements for eco-friendly coatings systems.

 Resistance to aromatic and aliphatic solvents

The resin from Evonik cures at ambient temperature, utilising a catalyst, which provides additional advantages. Application displays high and early resistance to aromatic and aliphatic solvents, in addition to impact resistance and non-blocking properties without a bake-cure cycle.

"Oven drying at high temperatures has natural limits," explains Kirstin Schulz, marketing director for industrial coatings. "Our ambient-curing systems enable coating of large objects such as in industrial plants for water treatment or for energy generation." Compared to classic bake-cure systems, energy consumption is also lower. Curing at room temperature facilitates a user friendly, economical solution to high-temperature resistant coatings.
