ASI335：
ASI 335醫療級矽橡膠：
ASI 335 Neutral Cure Silicone Sealant/Adhesive is a one-part, non-slump, moisture-curing RTV (room temperature vulcanizing) that cures to form a tough, high modulus rubber with long-term flexibility and durability.
ASI 335是一種中性、單組份、非坍陷,在潮濕空氣中固化的室溫硫化矽酮密封膠/膠粘劑，固化後形成一個韌性的、高彈性模量橡膠，並具有長期彈性和耐久性。
The neutral curing mechanism of ASI 335 is ideally suited for use in confined work areas since no objectionable odors are evolved.
ASI 335的中性固化機理由於其固化過程中沒有明顯的刺激性氣味而適用於密閉工作空間。
The non-slump characteristics of ASI 335 allow application to vertical or horizontal joints without flowing or sagging. ASI 335 has excellent resistance to weathering including ozone, ultraviolet radiation, freeze-thaw conditions and airborne chemicals.
ASI的非垂流特性允許其應用於垂直或水平的接縫而沒有流動或下垂。ASI 335同時具有良好的抗風化性能包括臭氧、紫外線輻射、解凍條件和空氣中的化學物質。
After cure, the wide heat stability range of ASI 335 is from -57°C to +204°C (-70°F to +400°F) and the sealant can be applied to surface temperatures from -18°C to +50°C (0°F to +120°F).
ASI 335可以應用於表麵溫度從-18°C到+ 50°C(0°F到+ 120°F)的物體表麵，且固化後的熱穩定性的范圍從-57°°C到+ 204 C(-70°F到+ 400°F)。
TYPICAL USES
典型應用
ASI 335 can be used as a durable, general-purpose sealant/adhesive in a wide range of industrial applications.
ASI 335可以在廣泛的工業領域作為一個通用的、持久的密封膠/膠粘劑。
Unprimed adhesion to a wide range of substrates is available with the use of ASI 335. For example, ASI 335 adheres to unprimed chrome and stainless steel, which other high modulus silicone sealants would require to be primed.
ASI 335可廣泛使用在無底漆粘膠的基片。例如，ASI 335可粘結到無底漆粘膠的鉻合金和不銹鋼，而其他高彈性矽酮密封劑需要塗底漆。
As a formed-in-place gasket, ASI 335 exhibits low swell, low compression set and good oil resistance. These characteristics impart an unusual balance of properties to ASI 335 to prevent leakage in harsh environments such as engines, transmissions, water pumps, rear axles and oil pans. ASI 335 is not recommended to be used in cylinder heads, exhaust manifolds or in contact with fuels.
ASI 335固化後形成一自適應密封墊,具備低膨脹/壓縮率和良好的耐油性能。這些特征使ASI335得以用於防泄漏在嚴酷的環境下,例如發動機、變速箱、水泵、後輪軸和油底殼。ASI 335不推薦用於氣缸蓋、廢氣再循環系統或直接接觸燃料。
DIRECTIONS
使用說明
ASI 335 is ready to use and requires no mixing or additives.
ASI 335已經可以使用,不需要混合或添加劑。
The cure mechanism begins as soon as the sealant comes in contact with air. At conditions of 25°C (77°F) and 50% relative humidity, the sealant will skin in 10-20 minutes and cure in 24 hours (1/8” bead), with full cure strength in 7 days. Higher humidity accelerates cure. Tooling should be done before skinning takes place.
ASI335一旦接觸空氣即開始固化。在25°C條件(77°F)和50%的相對濕度,密封劑將在10 - 20分鐘現成表麵固化層和並在24小時內現成約3mm的固化層，7天徹底固化。高濕度可加速固化速度。任何的加工需在表麵固化發生前完成。
In applications wher partial or total confinement of sealant is prevalent, the time required for proper cure is generally lengthened by the degree of confinement.
當應用於部分或完全密封條件下時，其固化時間的延長程度取決於其密閉狀況。
SURFACE PREPARATION
表麵準備
Providing that all bonding surfaces are clean and dry. ASI 335 has excellent unprimed adhesion to most substrates. It there is any doubt about contamination, surfaces should be solvent wiped with oil-free solvents, such as xylol, toluol, naphtha or non-flammable chlorinated solvents. Do not solvent-wipe with oil-based solvents such as Varsol.
所有的粘結表麵需保持清潔和乾燥。ASI 335對絕大多數的非底漆表麵具有優良的附著力。對於任何污染表麵，可采用無油的溶劑擦拭，如：二甲苯、甲苯、揮發油或不易燃的氯化溶劑。不可使用含油溶劑擦拭，如：烴類溶劑。
PRIMING底漆
Priming of ASI 335 is normally not required for application to most substrates. Unprimed adhesion can be readily tested by applying a small trial bead and allowing 7 days for maximum adhesion to occur. ASI 335 has excellent unprimed adhesion to many substrates as shown in the adhesion chart.
ASI 335對於大多數基質通常不需要底漆。無底漆的附著力測試可以很容易通過一個小試驗珠實驗來確定。ASI 335具有良好的無底漆粘附到許多基體上，見下表所示。
PAINTING
油漆
ASI 335 should not be applied to surfaces that will be painted. Painting over the sealant is not recommended because the paint film does not stretch with the extension of the sealant and the adhesion of paint to the sealant is not adequate.
ASI 335不可用於需油漆的表麵，因為漆膜不能隨著密封膠伸縮，在其表麵油漆是不可取的。
