SBR Technical Information

Plasterers Blend SBR – Technical Data

Not all SBR is the same. Plasterers Blend SBR is formulated specifically for plastering and construction applications. Our unique polymer selection delivers superior sealing, bonding, and cost efficiency compared to standard SBR products.

Polymer Chemistry Explained

  • SBR (Styrene-Butadiene Rubber) is produced by co-polymerising styrene and butadiene.

  • Styrene Content: Higher styrene = better rigidity and adhesion.

  • Butadiene Content: Higher butadiene = more flexibility, crack resistance, and durability.

  • Additional Co-Polymers: Acrylates or vinyl acetate can add water repellence, UV resistance, and substrate bonding.

Performance Benefits

Sealing Performance

  • High butadiene content reduces micro-cracking.

  • Hydrophobic co-polymers improve water resistance – ideal for external plastering.

Bonding Performance

  • Styrene-rich SBR delivers strong adhesion to concrete, brick, and blockwork.

  • Carboxylated SBR provides chemical bonding with cement for added strength.

Plasterers Blend SBR – Polymer Strategy

Bonding to substrate – Moderate styrene + carboxylation → Strong adhesion to masonry
Crack resistance – High butadiene content → Flexibility under thermal stress
Water resistance – Hydrophobic co-polymer → Reduced permeability
Workability – Optimised particle size & solids → Smooth application, reduced drag
Cost efficiency – Balanced polymer loading (5–10%) → High performance at low dosage

Commercial & Practical Advantages

  • Higher solids content compared to many competitors

  • Clear differentiation from “commodity” SBR products

  • Proven performance in UK & international markets

  • Growing demand from builders’ merchants nationwide

  • Premium branding supported by thousands of positive customer reviews

Plasterers Blend exemplifies how thoughtful polymer engineering can deliver superior plastering results with minimal material waste and reduced application time.

Summary

Plasterers Blend SBR is not just another bonding agent. It is engineered through careful polymer chemistry to deliver stronger adhesion, greater flexibility, and longer-lasting protection than standard SBR. With proven merchant success, consistent demand, and a growing brand reputation, Plasterers Blend is setting a new benchmark in plastering additives.
