this month's topic MaterialsAnti-Stick Agent Speeds Gasket Removal
A proprietary inorganic coating that facilitates the removal of gaskets from flanged joints, Flange Free is designed for use in high-temperature, critical-service applications. Gaskets treated with this material are easier to remove after extended use — in most cases, the effort takes seconds, not hours, and requires much less force than untreated gaskets. The coating is fused to the surface of the gasket material and does not contain chemicals that can cause gaskets to crack or otherwise degrade. Branding is applied with a specially formulated, water-based ink that prevents transfer to the flange.

Resins Offer Primerless Adhesion to Substrates
SPUR+ 3100HM prepolymer and SPUR+ 3200HM prepolymer silylated-polyurethane resins are high-performance, low-viscosity binding agents that impart high tensile strength to structural adhesives. They function without requiring primers for most substrates, and can be applied in both one- and two-part adhesive formulations. These additives provide excellent water and chemical resistance, as well as high thermal resistance. Their shelf life is about 12 months, and they are formulated without plasticizers and contain no free isocyanites. When cured alone, the SPUR+ 3100HM prepolymer has a tensile strength of 450 psi and a Shore A hardness of 40. The SPUR+ 3200HM prepolymer is designed for the most demanding applications, and can offer 1,000-psi tensile strength with a Shore A hardness of 60.

Versatile Color Pigment Enhances Shade, Shape and Design
The XYMARA Fireball “color-travel” effect pigment has very high durability, making it suitable for high-performance applications, including exterior automotive coatings and such consumer goods as mobile phones and electronic devices. This pigment highlights the shape of an object, and can vary its shade from orange/gold to deep cherry red, depending on the angle of observation. Its platelet character can add a discreet decorative sparkle when used in an effect color formulation. Inherent transparency makes it suitable for use in combination with different chromatic transparent pigments, as well as in multi-layer paint systems.

High-Conductivity Epoxy is Cost-Effective
Polymer system EP79 is a silver-coated nickel-filled epoxy with extremely low electrical resistance. Curing at room temperature yields an epoxy with a volume resistivity of less than 0.04 ohm-cm. Higher temperatures result in more rapid curing, which forms strong bonds with high shear and peel strength, plus resistance to thermal cycling, mechanical shock and vibration. EP79 has a 1:1 mix ratio, and a temperature range of –452ºF to 275ºF. It is an alternative to silver-filled epoxy and is available in premixed and frozen syringes, as well as in jars and cans of various sizes
