Ottoseal P300 polyurethane sealant white 600ml – case of 20

The case of 20 is the manufacturer’s original case containing 20 units of the same type. You pay less per unit than when buying singly, and the sealed case is delivered – ideal for trade businesses and larger projects.

Ottoseal P300 is a polyurethane sealant with high water vapour permeability. Ottoseal P300 polyurethane sealant offers weather and ageing resistance. Ottoseal P300 polyurethane sealant offers very good paint compatibility according to DIN 52452. The inexpensive Ottoseal P300 polyurethane sealant is particularly suited to sealing expansion joints and connection joints on precast concrete and aerated concrete elements, facades, metal constructions, terraces, balconies, windows. Ottoseal P 300 polyurethane sealant is an inexpensive PU sealant that meets the requirements of IVD leaflet no. 9.

Special notes:

Before using the adhesive / sealant, the user must ensure that the building materials in the contact area (solid, liquid and gaseous) are compatible with the adhesive / sealant and do not damage or alter it (e.g. discolour it). For building materials that are subsequently processed in the area of the adhesive / sealant, the user must clarify beforehand that their ingredients or emissions cannot impair or alter the adhesive / sealant (e.g. discolouration). If necessary, the user must consult the respective manufacturer of the building materials.

OTTOSEAL P 300 is not to be used for floor joints, for glass sealing, in sanitary areas and areas of permanent wetness, under chemical exposure, or in any areas outside our recommendation. Elastic joint sealants should in principle not be painted over the full surface. For sealing on painted surfaces and plastics, preliminary tests must be carried out or technical advice obtained. Bonding to the joint base must be avoided at all costs. Avoid contact with materials containing bitumen or releasing plasticisers, such as butyl, EPDM, neoprene, insulating and black coatings etc. The colours can be affected by environmental influences (high temperature, chemicals, vapours, UV radiation). This has no influence on the product properties. On uneven and porous bonding surfaces and/or at correspondingly high ambient temperatures and high ambient humidity, blistering may occur. To avoid this we recommend OTTOSEAL P 305.
For joints on marble and natural stone we recommend OTTOSEAL S 70.
OTTOSEAL P 300 is resistant to:
Water and seawater, aqueous cleaning agents, dilute alkalis, lime water.
OTTOSEAL P 300 is conditionally (only short-term) resistant to:
Petrol, oil, solvents, dilute acids, fats and lubricating oils.
OTTOSEAL P 300 is not resistant to:
Alcohol, acids and alkalis, asphalt, bitumen, organic acids and other strongly aggressive chemicals.

Pre-treatment:

Preparing the bonding surfaces. Compatibility: paints, varnishes, plastics and other coating materials must be compatible with the adhesive / sealant. Cleaning: The bonding surfaces must be cleaned and any contamination, such as release agents, preservatives, grease, oil, dust, water, old adhesives / sealants and other substances that impair adhesion, must be removed. Cleaner for non-porous
substrates: Cleaning should be carried out with OTTO Cleaner T, methylated spirits or other cleaners based on acetone or isopropanol, and with a clean, lint-free cloth. Cleaner for porous substrates: porous surfaces must be cleaned of loose particles mechanically, e.g. with a steel brush or a grinding disc.
Adhesion and pre-treatment: OTTOSEAL products are high-quality, highly specialised products that are characterised by excellent adhesion without a primer on numerous substrates. Because of the very specific applications and the large number of materials, the use of primers should be confirmed by appropriate tests. Use of primers: if the use of a primer
is necessary, the following procedure should be observed in order to achieve an optimum result: - Apply the primer with a lint-free cloth on non-porous substrates (metals), or with a brush on porous substrates (concrete). - Apply the primer thinly and
evenly - excess primer forms a film that impairs
adhesion.
Primers and OTTOSEAL OTTOCOLL adhesives / sealants. Please note: Our primers have been specially matched to OTTOSEAL OTTOCOLL adhesives / sealants in order to ensure optimum adhesion and optimum mechanical properties. The interaction between OTTO Primer and OTTOSEAL OTTOCOLL adhesives / sealants and their mutual compatibility has been approved by our laboratory.
