Koby goes Green

06 AUG 2018

From the exterior to the interior, to the professional or for domestic use, silicones are used in numerous applications in our daily lives.

Koby brand thus enhances the research and formulation of "User Friendly" (or ecological) products, introducing the Alcoxy AL-30 Neutral Silicone to the market.

Neutral Silicone AL-30 Koby is a low modulus and high elasticity silicone of Alcoxi technology with very good adhesion on most building materials such as: glass, concrete, aluminum, steel, copper, ceramics, wood and various plastics. AL-30 Koby is also highly recommended for outdoor use due to its stability to UV rays and high resistance to weather changes.

Neutral Silicone AL-30 Koby is a product that is friendly to the applicator, non-harmful and meets the latest and most demanding European standards. In contrast, oxime-neutral silicones release a dangerous harmful substance (MEKO) and therefore require certain application conditions: such as well ventilated areas and use of respiratory mask. In some European countries there are already regulations that require the withdrawal of these products from the market.

The Neutral Silicone AL-30 Koby complies with EN 15651 and represents not only a safe product for the applicator but also excellent performance. Neutral Silicone AL-30 Koby is a product prepared for the future.
