PROKOL ROCATHAAN HOTSPARY PA136-T WATERPROOFING SYSTEM

PROKOL ROCATHAAN HOTSPARY PA136-T WATERPROOFING SYSTEM

Description and application

 

Rocathaan Hotspray PA 136-T is a fast set, rapid curing, 100% solids, flexible, aromatic, two component spray pure polyurea that can be applied to suitably prepared surfaces as concrete, metal and wood. Its extremely fast gel time makes it suitable for applications. Rocathaan Hotspray PA 136-T possesses the following certificates:

 

Available certificates
- WRAS BS6920 Potable water – Intertek UK
- CE Certification EN 1504-2 – Intron SGS
- Fire report DIN 4102-1 – Exova Brandhaus
- Water tightness certificate – BDA
- KSW Certificate for Public Pools – Germany


Cab be used as protection /linning for swimming pools, basins, hot tubs, tanks, façades, etc. As a wear-resistant layer in industry and construction, including ramps and parking roofs. It is ideally suited to cut and cover tunnels, sub structure/below grade, roof refurbishment, and any structure requiring chemical and abrasion resistance.

 

Also suitable as finishing for a wide variety of shapes and applications. Is also often used to coat insulation material, such as EPS and foam. If desired, it can be finished with a colored finish.

Application information

 

This material must be applied utilizing high-pressure, heated plural component spray proportioning equipment. The proportioning equipment must be capable of supplying correct pressure and the for
appropriate hose length on a consistent base. The spraying properties have a significant influence on the reaction time, hardening time and treatment.

Reaction time ± 5 seconds (type 136-T /05)
Tack free 30 – 45 seconds*
Spraying temperature 80 – 85ºC
Hose temperature 75 – 80ºC
Spraying pressure Depending on the type of pistol and mixing
chamber.
- CS Pistol 130 – 140 bar
- AP Pistol 150 – 180 bar
Usage 1,12 kg /m2/mm. From 1 mm. The layer thickness applied partially determines the properties and must be adapted to the purpose. Consult the appropriate application sheets. Pools and
basins are subject to special conditions. Consult the technical manual for these applications.


Mixing ratio 1:1 in volume
Surface temp. Minimum +5ºC
Window time for next layers
- Solvent-free layers maximum after 48 hours.
- Solvent based layers with a minimum of 12 hours and a maximum of 72 hours.


The subsequent layer is to be applied within this time. Open times can be reduced as temperatures increase. If open times are exceeded, the current layer must be sanded and treated with a suitable
primer.
