Sand control techniques

Thin resin coating is about 5% of the total weight of the sand. When exposed to heat, the resin cures, resulting in a consolidated sand mass. The use of resin-coated gravel as a sand-control technique involves pumping the gravel into the well to completely fill the perforations and casing.

Manufacturing Process of Decorative Laminates

The manufacturing process is different for both solid color paper and Printed design layer as follows: a) Solid Colour Paper: They go through a process that impregnates them with more durable melamine resin. The durability is essential because the decorative layer must withstand wear and tear. Two big rollers ring out the excess resin.
