Product Description

ISOBAM is an alkali water-soluble copolymer of isobutylene and maleic anhydride. The material, which has a white, powdery appearance, has outstanding properties that conventional water-soluble polymers such as polyvinyl alcohol and cellulose derivatives have not yet achieved. ISOBAM reacts with chemicals such as sodium hydrate, ammonia and amine and can be used as an aqueous solution.

An important field of application for ISOBAM is metal processing, where it is used as a forging lubricant and quenching fluid. With excellent water resistance and tackiness, it can also be used as an adhesive, in glass fibers, as a binder for ceramic powders and in other applications.

Features and benefits

• Water-soluble polymer

• Solvent-free
• Non-Pigment Forging Lubricant (NPFL) additive
• Excellent heat and water resistance
• Environmentally friendly compared to oil

Applications

Metal processing

ISOBAM is used in metal processing as a forging lubricant to replace forging oils, and as a quenching fluid where it replaces quenching oils. In these applications, ISOBAM contributes to high production safety and product quality and prevents fire hazards and flying sparks.

Oil-based die lubricants with or without graphite cause severe contamination during hot forging as a result of heavy smoke generation. In forging shops, oil can leak out and contaminate the surroundings.

If, on the other hand, water-soluble, graphite-free hot forging lubricants based on ISOBAM are applied with a spray system, there are many advantages, such as no pollution of the environment, no settling of particles or no coagulation of the lubricant, since ISOBAM is water-soluble. In addition, water-soluble hot forging lubricants are more environmentally friendly and better for the working environment.

Features and benefits

• Improves processability of metal

• Spark and fire prevention
• Prevents corrosion
• Cooling improves steel morphology
• Reduced residue
• Less smoke and odor compared to oil-based lubricants
• Safer than oil, sparking fire prevention
• Health-friendly compared to oil

Adhesives

Aqueous solutions of ISOBAM are used to prepare polyvinyl acetate (PVAC) emulsions as protective colloids. Aqueous ISOBAM can also be added to the emulsion as an adhesive component. As a result of its high heat resistance and high tackiness, ISOBAM is used, for example, as an additive for PVA-based wood adhesives to improve the properties of chipboard.

Features and benefits

• Improvement in film rigidity and strength
• Improvement in bonding strength
• High initial tack
• High bonding strength
• Can be cross-linked to achieve superior water resistance

Binder for ceramics

In the production of ceramics, various additives and agents are used as dry mixes or slurries. The binder has the function to obtain a stable green strength of the pressed or cast part before cutting and firing. As a water-soluble binder and dispersant for ceramic powder in the slurry, ISOBAM improves the green strength, porosity and density of the parts.

Features and benefits

• Temporary binder and dispersants agent for ceramics

• Excellent green strength and flexibility at low dosage
• Enables better cutting, less scrap
• Suited for low viscosity slurry with good storage stability
• Water-soluble
• Clean burn-out with low ash content
• Improved compressive strength and flex strength

The types of ISOBAM include standard, amide ammonium salt, and imide.

The standard type of ISOBAM is used as a binder with excellent heat resistance and hardness. It is further characterized by an excellent dispersing effect, with high functionality of the carboxyl group in the molecule. Standard types have a molecular weight ranging from medium to high and are soluble only in alkaline solutions.
