Organoclay for adhesives

The exceptional high-temperature performance of organic bentonite-based grease enables it to meet the demands of harsh operating environments. The gel structure formed by the grease achieves high-temperature stability through the intertwining of organic chains and hydrogen bonding.

In thermogravimetric analysis (TGA), the temperature at which 5% weight loss occurs reaches 280°C, significantly higher than the 200°C of traditional lithium-based grease.

In practical applications, synthetic ester lubricants containing organic bentonite can achieve a drop point of over 220°C, passing the GB/T 4929 drop point test standard, and can be used long-term in engine blocks, high-temperature bearings, and other components.

Bench tests conducted by a certain automotive engine manufacturer showed that bearings using this grease, after continuous operation at 180°C for 1,000 hours, exhibited grease loss of only one-third that of traditional products, with bearing wear reduced by 40%, effectively addressing the industry-wide challenge of lubrication failure under high-temperature conditions.

In adhesive formulations, organoclay controls sag and improves gap-filling performance in structural and construction adhesives; the Pillar reference is organoclay rheology modifier for adhesive and grease applications. Applicable product grades are listed on organoclay grades for adhesive rheology control. The finished adhesive product context is described in organoclay-based adhesives — performance characteristics. The closely related sealant application is covered in organoclay for sealants — related rheology application. Formulation-level guidance is available in organoclay in adhesive formulations — concentration and mixing.
