  • Polyurethane (anhydrous) mix - have excellent adhesion characteristics and provides high resistance to chemicals.The remaining advantages include: thermal and light stability, elasticity, not capricious for the microclimate.However, strongly glued strips together.Often these formulations are used for buildings with a high mechanical load.
