Recombination vs. Mutation. Although genetic recombination was discovered following the formation of Darwin's theories of evolution, it is still claimed that mutations are the source of any natural variability.
A primer is required for. porous surfaces, high build and anti-slip finishes . CHEMICAL RESISTANCE. Wykamol Epoxy Floor Coating EP40 has excellent. resistance to fuels, oils and lubricants. All grades possess. good resistance to dilute acids, alkalis, detergents, salt and. sugar solutions.
They are not designed to be a total sealant. Conformal coatings are a breathable protective layer that will protect against the particular environment requirement but will also allow any moisture trapped in the circuit board to escape. The particular advantages of conformal coatings can be summarized as follows: 1  Insulating properties allow a reduction in PCB conductor spacing of over 80%. 2  Can help eliminate the need for complex, sophisticated enclosures. 3  Light weight. 4  Completely protect the assembly against chemical and corrosive attack.
