Major building product related uses of our limestone granules and powders includes: Adhesives and sealants; Bituminous Products and Plasters, Paints and Textured Finishes.
The function of calcium carbonate in adhesives and sealants is to reduce cost, improve processing characteristics and increase the durability of the finished product.
Longcliffe’s ground limestone fillers are used in areas where high loadings are essential such as ceramic tile adhesives (CTA’s), grouts and joint fillers – sometimes comprising up to 80% of the formulation. Special care is given to control large particles to provide smooth finishes.
Bituminous products such as asphalt are often used like cement in the construction and repair of roads, car parks, pavements and driveways.
Longcliffe supplies limestone fillers for use in bituminous roofing membranes, roofing felts, as well as mastic asphalt and polymer-modified mastic asphalt systems. Mastic asphalt has a long and successful history as a waterproofing medium for flat roofs, water tanks, basements and foundations, as well as a surfacing material for floors, pavements, car parks and bridge decks.
Fine, ground calcium carbonates from Longcliffe are incorporated in wide range surface coatings including decorative paints, textured finishes and plasters through to more specialist applications such as industrial and protective coatings and road-marking paints.
All these applications have their own particular requirements and furthermore, nearly all are embracing more environmentally friendly technology to reduce solvent usage and emissions. As a result both water-based and high solids systems have become increasingly important.
