Cytec Industries Inc. (booth 613) introduced two new products for field applied UV curable floor coatings. UCECOAt 7891 is a new high performance acrylated polyurethane dispersion for UV curable field applied matte coatings on wood, vinyl and vinyl composition tile (VCT).
UCECOAT 7891 dispersion allows for the development of low gloss formulations without the use of silicas or other particles and dead matte formulations with very low amounts of silica. This results in formulations with better shelf life, since the settling of particles is no longer a concern.
UCECOAT 7891 based floor coatings have a uniform, transparent matte appearance. Moreover, floor coatings based on UCECOAT 7891 exhibit a good balance of flexibility and hardness, thus providing good adhesion and coin resistance. Excellent solvent and chemical resistance are also provided.
EBECRYL 893 is a modified polyester acrylate specifically developed for UV curable field applied VCT floor coatings. EBECRYL 893 is low in viscosity, providing latitude in formulating for these low viscosity applications. It also provides resistance to yellowing upon cure and over its lifetime. VCT coatings based on EBECRYL 893 provide a good balance of properties such as cure speed, adhesion, hardness, and scratch resistance. Good chemical and solvent resistance and high gloss are also obtained with VCT coatings based on EBECRYL 893.
