Pangel® B20

1 of 9 products in this brand
Pangel® B20 is a rheological additive derived from sepiolite (hydrated magnesium silicate), with its particle surface organically modified to ensure compatibility with medium and low polarity systems or solvents. It forms a three-dimensional network of particles, enhancing the viscosity and thixotropy of the end product. In epoxy coatings, Pangel® B20 offers the option for partial or complete substitution of fumed silicas and organophilic bentonites typically used as rheological additives, presenting additional cost-effective benefits in formulations.

Product Characteristics

Pangel® B20  can be used as a thixotropic agent in plastisols and in products which must have pseudoplastic characteristics or a high yield strength suitable for the intended application as for example:sity at 5 rpm and penetration of a paraffinic oil as function of Pangel® B20 concentration.

  • By cold dipping
  • By spraying
  • As mastics
  • For coatings (synthetic leather)

Advantages Of Pangel® B20 in Epoxy Coatings

The use of Pangel® B20 presents the following advantages in comparison with fumed silicas and organophilic bentonites:

  • Improvement in wetting and film formation.
  • Provides better viscosity and cracking behavior.
  • Maintain the rheological properties during longer times.
  • Improvement in total formulation cost.

Effect Of Pangel® B20 on the Rheological Behaviour Of Organoclay Greases


Figure 1 shows the thickening effect of PANGEL B20 and the penetration of a lubricating oil thickened with Pangel® B20.

Plastisol Viscosity Graph

Plastisol viscosity as a function of the concentration of Pangel® B20

The effect of PANGEL products on viscosity varies in relation to the concentration and type of plasticizer. Generally speaking, Pangel® B20 develops higher viscosities; however, this cannot be extrapolated to a full plastisol formula. Viscosity stability is also a function of the plasticizer. Pangel® B20 is more stable in plasticizers such as long-chain phthalates and adipates.
