Waterborne coatings & solvent-based coatings
Since their first appearance on the market 25 years ago, waterborne coatings have gained more and more significance in coatings applications due to their advantageous properties. As a consequence of increasingly stringent environmental standards, waterborne coatings, which have an inherently low solvent content, continue to hold the pole position in the race towards ever lower VOC levels.
Industrial coatings are the workhorses for covering the widest range of applications – heavy-duty, can and coil, wood, construction, flooring and other coatings. These are generally either solvent-based or waterborne systems. The broad portfolio of MERACRYL® methacrylate monomers enables formulators to precisely calibrate resin properties, such as adhesion, metal protection or even preservation of natural wood.
Architectural & decorative coatings
Architectural coatings are widely used to protect wooden or concrete structures from bleaching, chalking and general deterioration. Protective and decorative coatings that require excellent film-formation, adhesion, durability and gloss properties are ideally formulated with methacrylate resins.
Architectural coatings for outdoor applications preferably consist of MERACRYL® MMA or n-BMA methacrylate resins, offering excellent weatherability and color stability. Desired film formation properties are obtained from the right mixture of hard (MERACRYL® MMA) and soft (MERACRYL® n-BMA) comonomers while MERACRYL® GMAA helps stabilize emulsion polymers. In the long run, methacrylate resins consistently demonstrate their advantages in applications where labor costs are a chief concern.
Automotive coatings combine an attractive finish with outstanding protection. Methacrylate resins, with their inherently excellent weatherability and scratch resistance, are ideally associated with diisocyanates to add flexibility to high performance coatings. Hydroxyesters like MERACRYL® HEMA and HPMA serve as anchor molecules for crosslinking with polyurethanes.
