Coating foam with Polyurethane

Over the last year we have been developing a process of coating foam with polyurethane. We are working with various foam companies to develop methods for coating all types of foam.

Using polyurethane and polyurea spray we are able to give foam substrates increased durability and impact resistance.

Typically foam products are quite fragile when not covered and fall apart very easily. Polyurethane coatings will provide an increased resistance to those stresses caused by bending and deformation.

In the past foam products have typically been covered by stitched pvc covers. These are time consuming to produce and limited to simple shapes. Polyurethane coatings can be sprayed onto any shape and retain intricate detail.

Bonding agent is applied to steel roller prior to the moulding process being carried out. Brush or spray application. Polyurethane is dispensed, placed under a vacuum to remove any enveloped air and poured into the mould cavity.
Excess polyurethane is faced of the roller on a lathe. This is part of the trimming operation.
Rollers are palletised and inspected ready for dispatch to the customer.
