siloxane room paint
SILFASIL is a matt, water-dilutable wall and ceiling matt paint for interior use. The advantages such as high opacity, high yield as well as the odourless, drip and deposit-free (thixotropic setting) processing make SILFASIL a popular and economical solution. SILFASIL Coatings dry out without leaving a trace, are extremely washable and abrasion-resistant – and remain breathable, low tension and resistant to yellowing.

SILFADUR is a scrub-resistant, cloth mat, solvent-based but low-odour ceiling mat paint for interior use. Due to the thixotropic setting, SILFADUR can be processed drip- and batch-free. SILFADUR has an enormously high covering power and insulating effect against water, smoke and nicotine stains. The cloth-mat surfaces remain breathable and low-tension. Due to its excellent adhesion and hardening effect, SILFADUR is also ideal for problematic renovations, such as those involving glue paint residues.
