Bluestar Silicones has launched Lyndcoat BR2430, a new semi-permanent inside paint and bladder coating.

The company said the product offers a semi-permanent inside paint and bladder coating with improved properties, improving performance while attaining bladder protection, slip and air bleed promotion.

Bluestar said Lyndcoat BR2430 enables a decrease in direct and indirect operating costs related to tire curing, achieving low defect rates. The company claims the product offers high air evacuation promotion and rub-off resistance, while greatly reducing buckled and pinched bladder defects and favors curing of perfectly symmetrical tires.

Bluestar said Lyndcoat BR2430 was developed to ensure durable release between tire and bladder, has low odor and is easy to spray. It is colorless and fully transparent when dry and does not present any oily surface aspect.

The firm said Lyndcoat BR2430 allows for strongly reduced build-up on bladder and metal parts of the mold, allowing for highly reduced mold pollution. The company said the product delivers high performance with reduced coat weight. Passenger car tires may be coated with as little as 4-10 grams wet weight of Lyndcoat BR2430, the company claimed.

APS Elastomers said it now offers thermoplastic elastomers deagglomeration, which is a size-reduction process in which loosely adhered plastic pellets are broken apart.

APS said that for soft TPEs, agglomeration can occur if the material is packed hot or if the pellets are under pressure because of the way it was packaged. APS claims deagglomeration ensures its pellets flow freely in our customers' processes.

APS said all soft TPE material shipped from the company's warehouse in Romulus, Mich., is inspected for agglomeration. APS Elastomers claims it has developed proprietary deagglomeration equipment, allowing resin to dry, mix and separate evenly.

Mahr Federal Inc. has introduced the MarCal 16 EWR, waterproof digital calipers featuring a new ergonomic design with lapped guideways and larger display.

The company said the MarCal 16 EWR offers IP 67 protection against dust, coolants and lubricants, has an extended three-year battery life, and offers a zero-reference system that automatically stores the zero position for further measurements.

The design of the digital calipers features a handy non-slip thumb support, the company said, and a large, high-contrast display with 11-mm digits for accurate reading. The firm said the IP 67-rated construction protects against dust and temporary water immersion and has excellent chemical resistance.

MarCal calipers have lapped guideway surfaces, the company claimed, providing an even, sensitive run of the slide that increase the service life of the caliper compared to ground guideways due to greater contact area on the guideway surface.

All Mahr digital calipers feature a reference system in which the zero position only has to be set once, according to the firm. After setting, the zero remains stored for further measurements, eliminating the need to reset zero every time the caliper is switched on, Mahr said.

The calipers are equipped with an electronic lock function. For more information, visit www.mahr.com.
