Carapax-Vergleich

Carapax - second to none

Compared with conventional systems (e. g. two comp. epoxy, two comp. PUR, chlorinated rubber, PVC-systems, synthetic resins) Carapax products provide unbeatable advantages thanks to their unique formulation:

 

 CarapaxEpoxY
PROCESSING

single-component

easy handling and application, ready to use, no mixing errors, shorter preparation time (stirring well is all it takes)

two-component

risk of mixing errors
longer preparation time
RECOATABILITY Quick-drying: Carapax can already be recoated after 45–60 minutes, the second layer is resistant after only ca. 24 hours. No maximum time limit for further recoating, which can take place without prior sandblasting after more than a year. Can only be recoated after 5–16 hours, but no later than after 10–24 hours, otherwise fresh sandblasting is required.
REPAIR-FRIENDLINESS Carapax is repair-friendly thanks to the good wettability combined with a very dense film formation – even after several years, both with itself as well as on other coatings!

Simple overpainting is not possible, extensive preparation (e. g. sandblasting or roughening of the surface) is required.

AIR-HUMIDITY Air humidity is not an issue for Carapax products, since they are moisture-curing, i. e. no interruption of work in critical weather conditions, drying and curing even at temperatures around freezing point and air humidity of up to 98 % (e. g. tropical conditions).

Epoxy systems can only be used up to a certain air humidity (usually to a maximum of 90 %).

PROCESSING TEMPERATURE Surface temperature – no problem. Carapax can be applied at temperatures from below 0 °C to 60 °C.

As a rule, epoxy systems require a temperature of at least 10 °C but not more than 35 °C.

ADHESION Polyurethane as a binder possesses an outstanding wettability, thus perfect adhesion, excellent resistance to chemical products and solvents, which results in an above-average durability, even in the challenging field of corrosion protection. Carapax even adheres to damp steel surfaces, e. g. ice-cold gas pipelines in tropical regions, which are always damp.

Very poor adhesion to moist and damp surfaces.

FLEXIBILITY / STABILITY Carapax is permanently tough-elastic and highly resistant. This enables the complete absorption of any deformation through material tension, temperature change, vibrations and mechanical impact. No cracks, no bursting.
The excellent adhesion and the permanently tough-elastic structure ensure corrosion protection with extreme mechanical stability and abrasion resistance.

Due to their crystalline molecule
structure, epoxy coatings tend to embrittle over time and crack as a result of mechanical strain, material tension through temperature change or vibration.

NON-POROSITY Even thin coats of 60–70 μm are free of pores.  
SEA/SALT WATER
UV RAYS
Carapax shows an excellent resistance
to sea/salt water and UV rays.
Epoxy resin coatings embrittle if
exposed to salt water or UV rays.

ECO-FRIENDLINESS The high volume of non-volatile matter in Carapax products combined with their longevity results in a considerably lower environmental impact, from application onwards, since the products are usually ready to use and do not require the use of thinners (except for the cleaning of tools and equipment). Epoxy resin products are two-component coatings and require thinners.
Due to the significantly lower
durability they also need to be  recoated much more frequently.
ECONOMIC EFFICIENCY Thanks to the extreme longevity combined with the excellent processing properties (preparation time, drying time, etc.) Carapax is unbeatably efficient!
