Rilsan Coated Bolts

Fasteners Rilsan® coated are the norm and the demanded fastener for the water and effluent industry. The fastener products normally coated are hexagon bolt, nut and washer assemblies and for the chemical industry, Rilsan coated studbolts.



Rilsan® PA 11 Fastener Coatings

Rilsan® PA 11 coatings may be applied to all types of steel fasteners. Polyamide 11 (PA 11) or Nylon 11 is a polyamide bioplastic, its properties are similar to PA12, although it has a lower environmental impact, consumes less non-renewable resources to be produced and has superior thermal resistance. It is weaker but more resilient than the most common types of Nylon 6 and 66.

Rilsan® Process 

Processing is quite simple and consists of depositing a Rilsan® film onto the metal surface of the fastener. Careful surface preparation is absolutely necessary beforehand if optimum performance is to be achieved with Rilsan® products. Following this pre-treatment, a primer may be applied to improve the adhesion of Rilsan® onto the surface of the fastener and maximize the anticorrosion properties. 

Rilsan® Coating Benefits

Rilsan®  has high corrosion resistance in water, wastewater and salt water, demanded by water authorities. 

Rilsan®  has high chemical resistance to hydrocarbons, solvents, acids, salts and alkalis. 

Rilsan®  outstanding features are abrasion resistance,  impact resistance, flexibility, thermal resistance, weathering and chalking.

Rilsan®  has low water absorption high dimensional stability, good resistance to stress cracking and a low coefficient of friction. 

Rilsan®  is an environmentally green product it is made from a renewable raw material, namely castor seeds 'castor oil'.
