    Guyblast

    Guyson Guyblast is a urea based thermoset resin granulated to produce jagged angular shapes that clean with a unique chipping and shearing action. Without the aggression of mineral or metallic media, this product is ideal for cleaning more delicate products or removing surface residue and coatings whilst leaving the substrate undamaged.

    It is the most common and popular of the “soft impact” plastic media and is often used for dry stripping on composite and aluminium products i.e. paint removal applications using pressure blast equipment at relatively low pressures.

    It is commonly known as US type 2 plastic media.

    Available to Rolls Royce CSS227 quality standard.

    Applications

    Paint, coating and carbon removal. Mould, die and tool cleaning. Removal of light flash from die castings or burrs from machined parts. Deflashing of electronic components.

    Flashgrit

    Guyson Flashgrit is a specially produced soft acrylic thermoplastic blast media, often specified for military and aerospace dry stripping i.e. paint removal applications.

    All product is manufactured to comply with US Military specification MIL-P-85891A and Rolls-Royce CSS227 standards.

    It is commonly known as US Type 5 plastic media

    Applications

    Removal of paint and coatings from aluminium and composite materials, whilst leaving the substrate undamaged.

    Guystrip

    Guyson Guystrip is an amino based thermoset resin, granulated to produce jagged angular shapes that clean with a unique chipping and shearing action. Bridging the gap between harsh mineral media and the soft natural products, Guystrip is ideal for cleaning more delicate products or removing surface residue and coatings whilst leaving the substrate undamaged.

    It is the hardest and most aggressive of the “soft impact” plastic media and is often used for dry stripping i.e. paint removal applications using pressure blast equipment at relatively low pressures. When used for cleaning or deburring without dimensional change, sharp edges are retained as the hardness of the product is significantly less than that of a machined metallic product or tool/die.

    It is commonly known as US type 3 plastic media.

    Available to Rolls Royce CSS227 quality standard.

    Applications

    Paint, coating and carbon removal. Mould, die and tool cleaning. Removal of light flash from die castings or burrs from machined parts. Deflashing of electronic components.

    Flashgrain

    Guyson Flashgrain is a polycarbonate thermoplastic product, produced from accurately cut extruded strands of polymer. Hard and non-abrasive, this is the toughest of the impact deflashing plastic products and it retains its cylindrical shape during blasting. Dust free during blasting, breakdown over long periods of use is minimal.

    Applications

    Deflashing standard thermoset and reinforced thermoset plastic mouldings and die castings, deburring machined metallic or sintered components.

    Flashbead

    Guyson Flashbead is a specialised non-abrading polystyrene thermoplastic product, produced for use where other deburring or deflashing products such as Thermoflash and Flashgrain are too large.

    Applications

    Deflashing thermoset plastic mouldings and die castings, deburring machined metallic or sintered components. Intricate deburring of fine slots and knife blade edges after grinding without sharp edges being affected.

    Thermoflash

    Guyson Thermoflash is a polyamide nylon thermoplastic product, produced from accurately cut extruded strands of polymer. Tough and resilient, it gradually rounds during blasting, but retains edges for most of its life. It is non-abrading and completely dust free during blasting. Breakdown over long periods of use is minimal.

    Applications

    Deflashing thermoset plastic mouldings and die castings, deburring machined metallic or sintered components.
