Radiacid 0950 is described as a “dimer acid” — meaning the fatty acid molecules (typically unsaturated C18 fatty acids) have been chemically combined (dimerised) to form higher molecular weight di-carboxylic acid species.

These dimer acids are used as building blocks or additives in polymers, coatings, adhesives, lubricants and other industrial applications because of their enhanced mechanical and performance properties (flexibility, adhesion, water-repellency, stability).

Because Radiacid 0950 is derived from vegetable fatty acids and offered as “100% vegetable based”, it is positioned as a renewable raw material option.
Radiacid 0950is a 100% vegetable based dimer acid that enhances the mechanical properties of polymers.
Radiacid 0950 has a wide variety of uses including coatings & inks, lubricants, adhesives, plastics, and elastomers.

USES and APPLICATIONS of RADIACID 0950:
Polymers & tyres: Radiacid 0950 is used to improve mechanical properties of polymers (flexibility, adhesion, water resistance) according to product data.
Coatings & inks: Radiacid 0950 is used in coatings & inks for water-repellency, pigment wetting, etc.

Adhesives: Radiacid 0950 provides enhanced adhesion and flexibility.
Lubricants & fuel additives: Radiacid 0950 is described as a fatty acid additive in lubrication formulations.
Plastics & elastomers: Radiacid 0950 helps in plastics modification, elastomers, improving flexibility and durability.

Cosmetics and Personal Care: Radiacid 0950 is used as an emulsifier and co-emulsifier in creams, lotions, and conditioners.
Radiacid 0950 enhances stability and texture in emulsions and increases the viscosity of oil-in-water systems.

Detergents and Cleaners: Radiacid 0950 acts as a surfactant and solubilizing agent to improve foam and cleaning performance.
Industrial Uses: Radiacid 0950 is applied in textile auxiliaries, metalworking fluids, and polish formulations due to its lubricating and dispersing properties.

BENEFITS & CHARACTERISTICS of RADIACID 0950:
Because Radiacid 0950 is dimerised fatty acid, the higher molecular weight and di-acid structure provide improved thermal/oxidative stability compared to monomeric fatty acids.
For example, Radiacid 0950 claims “high resistance to hydrolysis, thermo-oxidation, UV radiation”.
Radiacid 0950 enhances flexibility at lower temperatures.

Radiacid 0950 provides water-repellency (hydrophobic character) for coatings and materials.
Radiacid 0950 is used good pigment wetting and universal adhesion for inks/coatings.
Vegetable origin (renewable raw material) may be an advantage for “green” or sustainable formulations.

CHARACTERISTICS / FORMULATION CONSIDERATIONS of RADIACID 0950:
Because Radiacid 0950 is a wax-like or viscous high-molecular-weight acid, handling often requires heating or melting for incorporation into formulations (viscosity 7,500-9,000 cP at 25 °C) and low solubility in water.
As a dimer acid, Radiacid 0950 behaves differently from simple fatty acids — e.g., lower solubility, higher molecular weight, more hydrophobic/higher melting point.

Radiacid 0950 is used in coatings/plastics/adduct systems, compatibility with the polymer or resin matrix must be checked (polarity, miscibility).
Radiacid 0950 is used as additive may affect mechanical properties (flexibility, adhesion, hydrophobicity) — the formulator should test effect on modulus, elongation, adhesion, etc.
