Coatings World - April 2013

“As costs rise and customer demands increase, companies
need to operate more efficiently,” Reiser said. “We find the more
closely we work with our customers, the better we can bal-
ance their needs with our resources. Over the past two years,
Specialty Polymers has expanded both their sales and technical
group. These folks are working closer than ever with our cus-
tomers to ensure we clearly understand their application and
performance requirements. To meet the flexibility in delivery
volumes and lead times customers need, we’ve invested signifi-
cant capital in our production facilities.”
“At GP Chemicals, we continuously challenge ourselves to
assess how our products create value for the customer and what
might be done to create even more value,” Boyer said. “As in-
dustry costs rise as a result of REACH regulations and raw ma-
terial costs, we proactively communicate with our customers so
there is a general understanding and agreement of the cost/value
relationships facing the market.”

New Products

To meet the needs of their coatings customers, resin manufacturers are working overtime to develop new innovations.

BASF’s Joncryl PRO 1525 was introduced as a DTM and topcoat WB 1K resin with improved hardness and block resistance for high gloss(>80 at 60°) low film (<2 mils) light-duty industrial metal applications. To address the low VOC needs of the automotive refinish market, BASF launched Joncryl RPD 950-AC/P polyol for solventborne 2K polyurethane systems. Joncryl RPD 980-B targets the general industrial market, offering superior chemical resistance properties along with rapid set to touch, excellent dry hard and dry through characteristics.

One of Specialty Polymers’ new core shell resins is RayCryl 709, a self-crosslinking acrylic emulsion designed for low VOC coatings, sealers and stains on a wide range of substrates. Its unique core shell technology provides good water resistance and hardness with low coalescent demand. It has outstanding UV durability that allows it to be formulated into exterior coating for wood and cement based substrates. This small particle size, self-cross-linking emulsion provides excellent water resistant coatings with excellent film clarity.

Specialty Polymers’ RayCore 9534 is a new self crosslinking core shell acrylic urethane copolymer designed to exhibit good physical properties for concrete, wood, plastics and architectural. Due to the polycarbonate polyurethane dispersion the company utilizes in processing, the resin has excellent chemical and UV resistance. The product exhibits very good scratch resistance and adhesion.

Emerald’s CVC Thermoset Specialties business group launched a new series of HYPRO hydroxyl terminated reactive liquid polymers (HTBs). These HTB polyols may be used for production of soft, flexible urethanes, even at low temperatures with enhanced hydrolytic stability. According to Jeff Tyrrell, reactive liquid polymers product manager for Emerald’s CVC business group, these products are ideal for water-proof coatings and membranes, window sealants, encapsulants and adhesives. Two compositions are available – HYPRO 2800X95 and HYPRO1200X90.

Alberdingk Boley introduced LUX 255, a new UV curable PUD offering excellent scratch resistance, good chemical resistance and very fast water release with quick cure response, as well as U 7800, a new solvent-free PUD which can be formulated at low VOC, offering excellent abrasion resistance, good chemical resistance and high hardness.

Scott Cooley, North American coatings technology director at Reichhold, noted that a few examples of Reichhold’s low VOC, biobased products are BECKOSOL AQ210 and BECKOSOL AQ 521. BECKOSOL AQ 210 is an alkyd latex containing biobased oils, and does not require coalescing solvent for film formation. Metal primers formulated with this product match the performance of higher-end traditional solvent- borne alkyds. BECKOSOL AQ 521 is a low VOC epoxy modified alkyd latex made with biobased oils that gives a “wet look” appearance on porous concrete.

‘Green’ Technologies

There is strong interest in environmentally friendly, “green” technologies, and understandably, resin manufacturers are involved in developing more biobased products.
