Spheriglass® solid glass microspheres, a practical solution to managing your resin supply chain and rising formulation costs

Spheriglass solid glass microspheres from Potters offers cost and performance benefits when incorporated into epoxy, urethane, and many other coating systems. The addition of Spheriglass into industrial floor coatings or polymeric flooring tiles, will improve properties such as shrinkage and resistance to cracking. With today’s supply chain challenges, the incorporation of Spheriglass allows for significant cost savings by reducing the loading level of costly and lately difficult to source resins. The solid glass microspheres range in sizes from 5 microns up to 5 millimeters.

Common applications include transportation, automotive, chemical, electronic, industrial, and engineering industries. Solid microspheres are safer to use than other functional fillers which can contain crystalline silica. Spheriglass is amorphous and contains no crystalline silica! Also, the low surface area means little to no impact on formulation viscosity as compared to other materials.

Additional benefits include:
• Cost savings from reduced resin demand and lower material cost
• Enhanced surface hardness, scratch resistance and increased abrasion resistance
• Improved stain resistance and excellent chemical resistance
• Improved resistance to shrinkage and cracking
• High loading levels can be achieved without the need for high shear mixing.
• Tight particle size means no impact on surface finish.

For over 100 years Potters Industries has been a world leader in the manufacturing of glass beads. For more info about Spheriglass® or to request a sample call your Barentz Account Manager today at (440) 937-1000.

Easy-to-Disperse High-Jet Carbon Black Preparation for Waterborne Coatings

For years Orion Engineered Carbons has offered high performance Specialty Carbon Blacks for the CASE market. Specialty Carbon Black has always been considered one of the most difficult pigments to disperse into coatings. Thankfully, Orion Engineered Carbons offers a solution to this challenge - Colour Black OE 430W. Colour Black OE 430W is an extremely easy-to-disperse powder which provides a fast and simple approach to achieving highly concentrated Carbon Black pastes with broad compatibility. Designed for waterborne systems, this preparation allows for the highest jetness levels combined with very strong bluish undertones, high gloss, and low haze to be obtained.

Colour Black OE430W provides simple access to high jet water-borne coatings. It can be disperse directly into water and develop the final colorimetric properties within 15 to 20 minutes. A typical water-borne binder free paste formulation containing 13 % of Specialty Carbon Black can easily be prepared by mixing water, defoamer and COLOUR BLACK OE 430 W using a dissolver for 20 minutes. There is no need for intensive milling or addition of further wetting additives. The viscosity of the obtained paste is low. Fineness of grind is below 5 μm as required for automotive, refinish and many industrial coatings applications. Pastes produced with Colour Black OE 430 are very stable, with no measurable change’s weeks later.

Colour Black OE430W is a premium product. Looking at a solid pigment preparation from a cost/performance perspective might result in objections, but only at first glance. It is important to account for the hours and sometimes days of energy usage to mill carbon black, the savings from not needing wetting and dispersing additives which can be as high as 120% on carbon black loading and the downtime associate maintenance and cleaning. For those without milling equipment Colour Black OE430W is the perfect solution to develop high jet black waterborne coatings.

Additional benefits of this product include:

• Absolutely no milling required!
• No additional wetting additives needed to develop full color within 20 minutes.
• Easy to handle free-flowing powder with no dust.
• Excellent pigment stabilization providing highest jetness levels combined with a strong bluish undertone.
• Broad compatibility with most commonly used waterborne binder systems

VESTOPLAST Amorphous poly-alpha-olefins (APAOs)

With VESTOPLAST amorphous poly-alpha-olefins, Evonik offers a broad range of co- and terpolymers of ethylene, propylene and 1-butene as raw material for hot melt adhesives and various other applications. Due to Evonik’s unique production process, they are able to design polymers with optimal values for properties such as hardness, cohesion, melt viscosity, crystallinity, and rate of crystallization. Due to its amorphous and partly crystalline character, VESTOPLAST APAOs have a low density of around 0.86 g/cm³. In addition to regular, pure thermoplastic grades, they also offer unique reactive, silane-modified amorphous poly-alpha-olefins. The following are just some of the benefits in using VESTOPLAST.

• Excellent adhesion and hot tack properties
• Bonding to various substrates, especially on polypropylene without pretreatment
• Good cohesion and high thermal stability
• Excellent moisture and gas barrier behavior
• Very good hydrolytic and UV stability
• Chemical resistance, e.g. against battery acid
• Low density

VESTOPLAST is a valuable ingredient for a broad range of applications and is one of the major resins used for hot melt adhesives. Typical hot melt applications are wood working, hygiene, packaging, automotive, and textiles. Other applications include bitumen modification, wire & cable, sealants, and mattress construction.
