| Résumé : |
There is an increasing demand in the construction industry for environmentally friendly building products, as well as requirements for more durable coatings with enhanced performance. New developments and advances in synthesis capabilities provide the market with a myriad of polymers for the vertical elastomeric masonry coatings market. New polymer technology has been developed without the addition of alkyl-phenolethoxylate surfactants, NMP or formaldehyde that enables the formulation of low VOC elastomeric coatings for vertical masonry applications.
Coatings based on the new technology have the ability to withstand high pH environments due to improvements in alkali resistance. The high level of alkali resistance gives the coating the ability to be used as self-priming coating, primer or topcoat.
New elastomeric coatings exhibit excellent water and efflorescence resistance, reducing the lifetime maintenance requirements and costs associated with preparing and recoating. Lower water intake of the coating prevents water penetration into the building structure and enhances wet adhesion of the topcoat at the masonry substrate. Improved water resistance and adhesion properties protect the structure from water damage. High tensile and elongation provides coatings with superior crack resistance when compared to conventional architectural coatings. In addition, improved weathering and resistance to dirt pick-up keep surfaces clean, with a long-lasting, fresh appearance.
This technology is recommended for use in elastomeric primers and topcoats for masonry façades, as well as new/hot, aged or repainted surfaces including exterior walls, concrete, block, brick, stucco, fibre cement and exterior insulation and finish systems (EIFS).
Modifications to traditional styrene acrylic and all-acrylic chemistries have been implemented into development of new polymers for elastomeric applications. |
